+# TODO
+
+- [ ] Implement `execute_withdraw(env, caller, proposal_id)` in `contracts/contracts/proposals/src/lib.rs`
+  - [ ] Verify caller is a treasury member (via treasury client)
+  - [ ] Verify proposal status is `Approved` (and not Executed)
+  - [ ] Verify treasury has sufficient balance
+  - [ ] Call `TokenClient::transfer` (or treasury/withdraw path consistent with repo)
+  - [ ] Deduct balance from `DataKey::Balances`
+  - [ ] Set proposal status to `Executed`
+  - [ ] Emit `WithdrawEvent` and `ProposalExecutedEvent`
+- [ ] Add/extend treasury interface(s) in proposals contract to match the needed calls
+- [ ] Add unit tests covering acceptance criteria:
+  - [ ] Pending proposal panics with "proposal not approved"
+  - [ ] Already executed proposal panics
+  - [ ] Balance correctly reduced after execution
+  - [ ] Non-member caller panics
+- [ ] Run contract tests (`cargo test -p proposals` and any other affected crates)
+- [ ] Create new git branch `blackboxai/...`, commit changes, and push to GitHub

-//! Covers every acceptance criterion from the issue:
-//!   - `finalize_proposal` before expiry panics
-//!   - Correct status set based on vote tally
-//!   - `execute_proposal` panics if status is not `Passed`
-//!
-//! Plus the obvious adjacent rules: voting after expiry / re-voting /
-//! double-finalize all panic; the `yes_votes <= no_votes` rule resolves
